The upper or male die 35 consists of an annular flange having a series of radially extending flanges sub-dividing the die into a series of sector shaped walled areas equal in number to the number of receptacles in molds 38 and 53 (Figs. 3 and 11). These flanges co-act with the corresponding flanges of either mold to compress the layers of dough therebetween (see Figs. 6, 8, 9 and 10). The annular and radially extending flanges may be serrated as indicated at 44 (Figs. 5, 6 and '7) in which event the peripheral marginal edges of the sector shaped pies will when finished have an undulatory crimped appearance more nearly simulating the appearance of a home made pie somewhat as shown in Fig. 12. A series of cutters 45 are affixed along the middle of the flanges of the male die 35. These cutters project below the flange as indicated in Figs. 5 and 6, and serve to sever the upper and lower layers of pie 46 and 48 along the middle line of the flanges of the lower mold (indicated by beads 54 of mold 53Fig. 11) to sub-divide the large pie with wastage into a plurality of individual sector shaped pies" equal in number to the number of spaced receptacles.

The rimmer 31 as shown is an annular cutter for trimming off the excess dough overhanging the edge of the pie plate (see Fig. 5), to produce the trimmed edge of Fig. 8, 8, 9 or 10.

In order to understand the principle of operation it may be advisable to consider Figs. 3, 5 and 13 together. A large sheet of dough 46 is first placed upon the pie plate 38 to overhang the edge thereof and is then lined against the walls of the several receptacles by means for example of a matrix consisting of a series of sector shaped projections each conforming in configuration to the configuration of the inner walls of the receptacles 43 of the plate 38 or receptacles 55 of plate 53. One suitable form of matrix for this purpose is disclosed in my Patent Number 1,841,507, granted January 19, 1932. The sweetmeat 4'7 is now placed in the dough lined receptacles which are then completely covered by the upper sheet of dough 48. The raw unfinished pie now resembles in general appearance the pie shown in Fig. 5. The pie plate 38 is now centered on the bench 21 relative to the male die 35 by means of the intersecting ribs 39 engaging the channels formed in the underside of the pie plate 38. Lever 40 is now operated and male die 35 moves downwards followed by rimmer 31, until the pie pan 38 (which in effect now constitutes a complementary female die), male die 35, and rimmer 31, assume the position indicated in Fig. 5, in which condition the dough overhanging the edge of plate 38 as shown in Fig. 5 is trimmed off and removed by the rimmer 31; cutters 45 of male die 35 (Fig. '7) separate the large pie along the radial partitioning walls of the pie plate 38 (or 53-Fig. 1) and the flanges 44 of the radial and peripheral walls of male die 35 engage and compress the upper and lower layers of dough 48 and 46 throughout their entire periphery to crimp the entire peripheral marginal edge of each individual sector shaped pie so as to completely seal the sweetmeat 4'7 of each individual pie in a shell like housing of dough.

The undulations 44 more nearly simulate in appearance the crust of the home made crimped pie, as is illustrated in Fig. 12; but these undulations 44 may be omitted from the male die 35 if preferred The pie may if preferred be so formed that the upper layer of dough 48 will be convex as best indicated by the cross section of Fig. 13.

The rimmer 31 is bevelled so that its sharp lower edge is of larger diameter than the pie pan 38, but as the width of the rimmer 31 increases its internal diameter decreases until at the top the rimmer is preferably of smaller diameter than the pie pan 38, so that the trimming of the waste dough is assured without permitting the sharp edge of rimmer 31 to engage on the top of pie pan 38 or upon the bench top 21. The varying internal diameter of rimmer 31 allows for commercial variations in the diameter of the pie pans 38. as the rimmer must be designed to operate with pie pans having such commercial variations of diameter.

The rimmer 31 may be rotated during or after its descent by the manual operation of handle 34 whereby the rimmer is caused to turn with its hub 36 relative to shaft 24, the bevelled wall of rimmer 31 operating to smooth out the trimmed edge of the layers of dough 46 and 48 thereby still further tending to obliterate any appearance of separate layers of dough.

The male die 50 (Fig. 10) is similar to male die 35 (Fig. 6) but does not include the serrations 44 (see Fig. 7). lhe radial partition walls 52 of male die 50 are united at the center to a hub 51 upon which the die may be securely mounted upon the shaft 24.

What is claimed is:

1. In a pie finishing machine and in combination, a male die member having a downwardly extending wall encircling the die, a series of equally spaced partition walls forming inwardly projecting radial extensions of said annular wall and joined together at the centre, said annular and partition walls in conjunction thereby defining a plurality of sector shaped walled areas each substantially equal in area to a standard sector shaped individual pie portion, the faces of all of said walls lying in the same horizontal plane to constitute means operable to compress the dough, a series of cutters equal in number to the number of partition walls and secured to and along the centre lines of the faces thereof and projecting therebeyond to the outer edge of the face of the annular wall, to define a plurality of open V shaped cutting members equal in number to the number of sector shaped receptacles having their cutting edges lying in the same horizontal plane, a rimmer encircling and rotatably mounted relative to the die encircling wall, a multi-unit pie plate for containing one large pie said plate forming one of a series of interchangeable female dies complementary to said male die, and being sub-divided into a plurality of spaced receptacles each receptacle being triangular or sector shaped and having a bottom wall, side walls constituting partition walls between adjacent receptacles, and a back wall, adjacent partition walls converging so that their upper edges define v shaped seats operable when said dies are brought into co-operative registry to co-act with the open V shaped cutters of the male die to subdivide the large pic into a plurality of indi vidual pies equal in number to the number of spaced receptacles, and the partition and back walls in conjunction defining triangular or sector shaped seats operable when said dies are brought into co-operative registry to co-act with the triangular or sector shaped dough compressing means of the male die to horizontally compress the upper and lower marginal edges of said individual pies throughout the entire periphery of each of them in the operation of forming the same, and means for bringing said male' and female dies into cooperative registry to effect said sub-dividing and compressing operations.
